When using vtkm::dot on narrow types you easily rollover the values.
Instead the result type of vtkm::dot should be wide enough to store the results
(32bits) when this occurs.
Fixes#193
MultiBlock now uses `diy::reduce` for reductions rather than using proxy
collectives. To support using `diy::reduce` operations on a
vtkm::cont::MultiBlock, added AssignerMultiBlock and
DecomposerMultiBlock classes. This are helper classes that provide DIY
concepts on top of a existing MultiBlock.
1. Add option to copy user supplied array in make_ArrayHandle.
2. Replace Field constructors that take user supplied arrays with make_Field.
3. Replace CoordinateSystem constructors that take user supplied arrays with
make_CoordinateSystem.
Updating MultiBlock to use `diy` for computing block summaries like
ranges, bounds etc. This makes it possible to MultiBlock to
work in distributed operations without explicit logic.

The intel compiler could not generate code in a timely manner ( 12+ hours ) when
asked to produce a cross product of very long lists. By moving to a lazy
evaluation scheme we now have all compilers product a cross product in a
reasonable amount of time ( 2-4 seconds ).

Previously we allowed a const ref as we would make a copy, this only works
as it relies on RuntimeDeviceTracker implementing state through a shared_ptr.
Instead if we require modifiable types only we can make TryExecute more
efficient and clearer on what it does.
By using perfect forwarding we can reduce not only the amount of TryExecute
signatures, but we can enable the ability to pass temporary functors to
TryExecute.
At the same time we have optimized TryExecute by moving the string generation
code into a single function that is compiled into the vtkm_cont library.
The end result is that the vtkm_rendering library size has been reduced from
12MB to 11MB, and we shave off about 5% of our build time.
